Indianapolis police have arrested a second teen in connection to a July shooting that left three people dead in a north side apartment.

Devante Gilbert, 18, was taken into custody on a warrant for robbery after surrendering Tuesday afternoon withhis attorney at IMPD headquarters.

The IndyStar has reached out to officials for more information about the circumstances of the shooting and Gilbert's alleged involvement in the incident.

He joins a 15-year-old boy as a suspect in connection to the deaths of Dominique Miller, 25; Jordan Wright, 25; and Justin Crowder, 19, on July 16 at an apartment in the 7800 block of Somerset Bay.

Police said the shooting involved illegal drugs, and that the suspects were after the contents of a safe. Witnesses told police that when the shooting stopped, people could be seen fleeing the apartment in a car.

Police confirmed that the 15-year-old did not live at the apartment, but additional information about what happened in the apartment in the moments leading up to the shooting has not been made public.

he 15-year-old could be the youngest triple homicide suspect in Indiana history. Interviews and checks of newspaper archives revealed no recent precedent. IndyStar typically does not identify juveniles accused of a crime unless their cases have been waived to adult court.

A decision on whether or not the teen will be tried as an adult has not yet been made.
